Countdown days, hours, minutes to 0

[safehome]

I have a start date and a duration. The duration is in the format of d:hh:mm. I am trying to countdown the d:hh:mm to 0. Not having much luck without using an end date. If anyone has suggestions please let me know. The other option would be to calculate the end date based on current date and adding in the d:hh:mm. I can do this in multiple cells doing day, hour, minutes separate but can't figure out how to do it in 1 cell.

Help with either option would be appreciated.

Thank you

Paste in a Routine Module :

Option Explicit


Public bTimerOn As Boolean


Sub ToggleTimer() ' This Sub will switch the automatic timer on if it was off before, and vice-versa
bTimerOn = Not bTimerOn


Refresh ' It calls the Refresh Sub
End Sub


Sub Refresh() ' This Sub calculates the sheet and tells Excel to call it again after 1 second
Application.Calculate


If bTimerOn Then ' If bTimerOn is True, start refreshing automatically
Application.OnTime Now + TimeValue("00:00:01"), "Refresh" ' The intervall is set to 1 second but can be changed variably
End If
End Sub
